Description

Technical Field

[0001] The utility model belongs to the technical field of transmission equipment, and particularly relates to a new coupling used for a high-speed rotating test bench. Background Art

[0002] The coupling is a mechanical part used to connect two shafts (driving shaft and driven shaft) in different mechanisms so that they rotate together to transmit torque. In high-speed and heavy-load power transmission, some couplings also have the functions of buffering, vibration reduction and improving the dynamic performance of the shaft system.

[0003] The coupling of the high-speed rotating test bench has the characteristics of high speed (16000r / min), frequent disassembly, small load torque, small vibration, etc. The coupling suitable for high speed generally uses the diaphragm coupling. The diaphragm coupling requires high precision, and frequent disassembly will reduce the precision, so the diaphragm coupling is not suitable for frequent disassembly. Other couplings that can be frequently disassembled cannot meet the high-speed requirements (pin couplings, gear couplings, etc.). In order to meet the high-speed and frequent disassembly requirements of the coupling of the high-speed rotating test bench, a new coupling for the high-speed rotating test bench is specially designed to solve the above problems. Utility Model Content

[0004] In order to solve the above technical problems, the purpose of the utility model is to provide a new coupling for a high-speed rotating test bench, which meets the requirements of the high-speed rotating test bench for the coupling, namely, high speed and frequent disassembly. Specifically, a coupling for a high-speed rotating test bench is provided, which is used to connect the drive shaft 1 at the motor end and the working shaft 8 of the test bench, including a drive end half coupling unit and a non-drive half coupling unit, wherein:

[0005] The driving end half coupling unit includes a flange A2 and a key 3; the flange A2 is sleeved on the periphery of the driving shaft 1, and the driving shaft 1 is connected and matched with the flange A2 through the key 3 to transmit torque;

[0006] The non-driven half coupling unit includes an inner tapered sleeve 7, a flange B6 and a screw 9; the inner tapered sleeve 7 is sleeved on the periphery of the working shaft 8, the flange B6 is sleeved on the periphery of the inner tapered sleeve 7, the inner tapered sleeve 7 and the flange B6 are matched through a conical surface structure, and one end is screwed into the screw 9 for fixing, so that the inner tapered sleeve 7 is wedged between the flange B6 and the working shaft 8, and the three parts are wedged together by interference fit;

[0007] The two half-shaft couplings are connected through flange A2 and the end of flange B6. Specifically, the mounting hole of flange A2 and the mounting hole of flange B6 are positioned and connected by installing a wooden pin 5. A fixing hole is left in the middle of 5. The rope 4 is continuously passed through a circle of fixing holes on the wooden pin 5, and finally the rope is tied.

[0008] Furthermore, a mounting groove is provided on the inner diameter surface of the flange A2, and the mounting groove is used to install the key 3. The mounting groove and the key 3 have an axial mounting gap, and the gap can be axially adjusted for installation without the need for high-precision dimensional matching.

[0009] The advantages of the utility model are: simple structure, suitable for high-speed rotating equipment. The wooden pin is used for positioning connection, and the wooden pin has good elasticity, which reduces the centering accuracy requirements of the high-speed coupling. In addition, due to the requirements of the use of the rotating test bench, the experimental product needs to be loaded into the experimental equipment from both ends of the working shaft. The inner tapered sleeve of the non-driving end and the non-driving end flange B are matched through the conical surface structure. The screws are screwed in so that the inner tapered sleeve of the non-driving end is wedged between the non-driving end flange B and the working shaft. The three pieces are wedged together by interference fit, and the disassembly is reversed. This structure is easy to assemble and disassemble, does not damage the working shaft, and is easy to use.
